Patent JP-H06232774-A (JP)
Title: Demodulation system
Inventor: MIZOGUCHI SHOICHI
IPC: H04B1/10
Filed: 1993-02-02
Abstract: PURPOSE:To overcome a defect of a demodulation system in which an adaptive matching filter(AMF) is set to a pre-stage of a discrimination feedback equalizer(DFE) that the equalization characteristic of this system is inferior to that of only a DFE against minimum phase shift fading. CONSTITUTION:A demodulator 11 demodulates an IF modulation signal and outputs an analog base band signal. An A/D converter 12 converts the base band signal into a digital signal. An AMF 13 receives an output of the A/D converter 12 to make an impulse response of a propagation line symmetrical. A DFE 14 receives an output of the AMF 13 to eliminate an inter-code interference. An AMF reset circuit 15 discriminates a type of fading based on a tap coefficient in the DFE 14 and controls the AMF 13 to stop its operation in the case of minimum phase shift fading (0<rho<1). Thus, the equalizing characteristic of minimum phase shift fading is improved.

CONSTITUTION:Through a batcher plant 44 set at the upper section of a travelling route 4 set on an inclined surface 2, concrete is delivered to the hopper 11 of an incline trunk 5. Then, the incline truck 5 is moved along the travelling route 4, and is stopped just in front of a bucket carrier truck 6 stopped within the working radius of a crane 45. Then, the concrete is thrown into a concrete bucket 34 on the bucket carrier truck from the hopper 11 of the incline truck 5, and is carried to a cast point with the crane 45. As a result, the suspension- exchange work of the concrete bucket is omitted, and working at a high place is conventional system is not needed.

Title: Ion beam irradiation device
Inventor: SAITO NORIO
IPC: H01J37/317
Filed: 1986-01-29
Abstract: PURPOSE:To change the depth of etching in accordance with the location of a deflection region by a method wherein a means, with which the distribution of the integral value of irradiation dose in a field (deflection scanning region) will be changed, is provided. CONSTITUTION:The output of a Y-deflection power source 16 is levelled up to a positive signal by a level shifter 9, and it is inputted to an amplifier 7. The output of the amplifier 7 is formed into a delta-shaped waveform (the highest value is in the range from several tens volts to several hundreds volts) of Vmod. If the output of an accelerated power source 6 is maintained at the DC high voltage (normally 5kV or thereabout) approximate to Vth (ion beam is in the state of cut off) and the output of the amplifier 7 is applied in a superposed manner (Vth+Vmod), a Y-deflection signal is increased on a sample 14, and at the same time, the intensity of the ion beam is increased. Accordingly, an oblique etching can be performed on the sample. The degree of obliqueness can be changed easily by changing the degree of amplification of the amplifier 7. According to this constitution, the sectioning of a microscopic part can be performed, and an arbitrary cross-section can be exposed in the depth direction by properly selecting the irradiation dose of the ion beam.

Title: Power supply method of signal extracting circuit
Inventor: NARA KOUICHI
IPC: H04J3/00
Filed: 1984-01-31
Abstract: PURPOSE:To prevent waste power consumption by providing a means to control power of a signal extracting circuit through the result of discrimination of a synchronism discrimination circuit in a synchronism terminal station device detecting a synchronism pattern on a data string so as to attain synchronism thereby stopping the power of the signal extracting circuit during the operation of synchronism locking. CONSTITUTION:A power voltage is supplied to the signal extracting circuit 3 from a power supply 4 via a transistor (TR). A synchronism discrimination circuit 2 supervises the synchronism state of a synchronism terminal station device and when the synchronism is not established, the circuit 2 gives logical 0 to a base of the TR via an NOT circuit 5 so as to cut off the TR thereby stopping the supply of power voltage of the signal extraction circuit 3. When the synchronism is estabilished, the circuit 2 gives logical 1 to the base of the TR via the NOT circuit 5 so as to activated the TR thereby supplying the power voltage to the signal extraction circuit 3. Thus, in case of out of synchronism of the synchronism terminal station device, the power of the signal extraction circuit for attaining ineffective operation, then waste power consumption is prevented.

IPC: H04L69/40
Filed: 1986-01-28
Abstract: PURPOSE:To supervise normalcy of data transfer by supervising the state of output signals of a flip-flop by a processor that transfers data serially synchronously with clock signals. CONSTITUTION:A processor 1 transfers data periodically. At first, the processor clears a shift register 7 and an RS-FF 9, and adds information of '1' prior to data and starts transferring.

Title: Fault detection processor
Inventor: TANAKA TADAAKI
IPC: G06F11/30
Filed: 1989-01-26
Abstract: PURPOSE:To detect the faults despite the mixture of different detecting conditions by using a lower rank fault detecting means which computes an exclusive OR between a fault monitor memory and a lower rank fault memory and at the same time outputs the result of the detection as long as no higher rank fault occurs. CONSTITUTION:A higher rank fault detecting means 71 detects a state where the higher rank faults occur twice and continuously. At the same time, a lower rank fault detecting means 72 detects a state where a difference is produced between the lower rank fault memories 32 and 42, i.e., the occurrence of a lower rank fault. Then the means 72 computes an exclusive OR between the result of the detection and a higher rank fault memory 31 and therefore does not output the result of detection for occurrence of the lower rank fault in case a higher rank fault is detected. Then an update discontinuing means 61 functions to discontinue the update of the memory data stored in the memory 42 of a 1st last look memory 40. Thus it is possible to detect the fault in a simple constitution where no fault counter is used despite the mixture of different fault detecting conditions.

Abstract: PURPOSE: To smoothly, accurately carry out titled control before and after changing the thickness of traveling rolled strip, by temporarily interrupting the action of the automatic absolute thickness value controller during the transition period, and by restarting before or at the same time as the end of changing thickness of the traveling strip.  
     CONSTITUTION: The automatic absolute thickness value controller 5 operates the signals set from the screw position detector 3 and the rolling load detector 4 in order to obtain the thickness of strip 1 on the run-out side of the rolling mill 2; thus obtained thickness is compared with the aim thickness value sent from the run-out side aim thickness setter 7; the screw position is controlled so as to make zero the difference obtanined by the comparison during the normal rolling condition; under this normal condition, if the thickness of traveling strip is to be changed, the input unit 8 for inputting the timing of changing thickness of traveling rolled strip inputs the thickness change start signal to the conroller 5 which hereby interrupts its normal controlling action temporarily. Next, before or at the same time as the end of rolling work for the thickness changed traveling strip, the unit 8 inputs the thickness change end signal to the controller 5; at the same time, the controller 5 restarts its action just after or a specified time after receiving a new aim thickness value from the setter 7 and controls the drive of the screw driving controller 6.
